Organoleptic and Chemical Changes during Storage of Sea Bass Marinades (Dicentrarchus labraxL., 1758)

Chemical and organoleptic changes in sea bass (Dicentrarchus labrax) preserved at 4C for 200 days have been investigated in this study. To prepare the fish fillets for study, they were put, at a ratio of 1:1.5 (fish:marinade brine), for marination into the brine containing 11% salt and 3.5% acetic acid. After the maturation process, samples were divided into two groups and packed in sealed plastic containers as plain and sauced and preserved for 200 days. At both groups packed as plain and sauced, TVB-N, TBA, TMA-N and peroxide number values were at acceptable limits during the storage of 200 days. It can be determined that both of the groups were approved in organoleptic terms; however, the sea bass marinades packed as plain were better approved. Our study shows that sea bass marinades packed as plain and sauced can be stored for 200 days without any quality problems. Practical Applications As the processed products are easy to store and bring a large margin of profit and always ready for the market, developing new products will contribute greatly to the aquaculture processing sector. Marinade processing technology is one of the cheapest technologies in aquaculture products processing and preservation methods, and it is very important in that it enriches the taste of fish, adds flavor and provides a longer shelf life. In the Mediterranean countries, sea bass ranks first in saltwater aquaculture and is among the most important aquaculture products. However; making use of the fish, especially which could not be sold or are undersold in the yield period, with the help of alternative processing methods can contribute to producers, the fisheries processing sector and the national economy. It was determined that sea bass marinades packed as plain and sauced can be stored for 200 days and can still retain their quality.
